YouTube has brought back this feature properly now.

Thanks to everyone who used this extension and especially those who contributed with issues and PRs. It was a fun run.

This browser extension returns the Youtube Sort By: Oldest feature. It basically inverts the videos with a animation overlay(which can be disabled in settings).

• Microsoft Edge support pending
• If channel has many videos loading time will be long.

Basically when /videos is found in the url it activates contentScript.js. It then creates the button on a 1s delay which allows the DOM to fully load. Once the button is pressed, it injects styles which is css that includes flex-direction: column-reverse and flex-direction: row-reverse which reverse the contents.

1. Download latest release .zip file
2. Go to extension manager in browser and enable Developer mode
3. Click Load unpacked and give the path to the extracted files.

• reverse engineer api or use animations to cover loading time, if possible.
• Website needs alot of work, help with that would be great :)
• contentScripts.js needs to be refactored.
